Abstract: A rating scale measuring parent beliefs about play was developed and validated with a sample of 224 African American mothers of children attending Head Start. Principal components analyses of the Parent Play Beliefs Scale (PPBS) revealed two factors, Play Support and Academic Focus, which capture parent attitudes regarding the developmental significance of play. Maternal ratings of Play Support correlated positively with ratings of children's interactive peer play and were positively associated with parent education. Maternal ratings of Academic Focus were negatively correlated with prosocial peer play ratings and positively correlated with ratings of disruptive and disconnected play in children. Findings support the psychometric utility of the new measure. Future directions involving parent play beliefs in conceptual models of children's social competence during early childhood are discussed.
